摘要

In recent years as increasing the demand for electricity, the existing energy sources may not sufficient to satisfy the electrical demands, and responsible for polluting the environment. In order to meet the electricity demands, and maintain environment with pollution free. So people are focusing on renewable energy sources. For grid integration and AC load applications high voltage is needed as per the demand levels. Actually to increase the voltage levels high gain DC-DC or DC-AC converters and transformers are required. So to clear these problems, this paper introduces a reduced switch multi level inverter, it works on the asymmetric voltage sources and less no of switches for the application of renewable energy systems. A level shifted pulse-width modulation (LSPWM) scheme will be used in the proposed topology. The performance of this inverter can be validated through MATLAB/Simulink-based simulation results.
